The distance between transmitting antenna and receiving antenna at which they can see each other is called ……….

A transmitting antenna of height 25 m is fitted at the top of a tower of height 20m. What is the height of the receiving antenna from ground level if the maximum distance between transmitting antenna and receiving antenna on ground is 56 km. Radius of earth = 6400 km.

What does the term LOS communication mean? Name the types of waves that are used for this communication. Which of the two height of transmitting antenna and height of receiving antenna can effect the range over which this mode of communication remains effective?

The height of a transmitting antenna is 68 m and the receiving antenna is at the top of a tower of height 34m. Calculate the maximum distance between them for satisfactory transmission in line of sight mode, R = 6400 km

The maximum range for the tropospheric transmission of radio wave of wavelength 3m using the transmitting antenna and receiving antenna of heights 100 m and 60 m respectively is

In a line of sight radio communication, a distance of about 50 is Kept between the transmitting and receiving entennas. If the height of the receiving antenna is 70m , then the minimum height fof the transmitting antenna should be: ("Radius of the Earth"=6.4xx10^(6)m) .

In a line of sight radio communication, a distance of about 50 is Kept between the transmitting and receiving entennas. If the height of the receiving antenna is 70m , then the minimum height fof the transmitting antenna should be: ("Radius of the Earth"=6.4xx10^(6)m) .

A T V transmitting antenna is 80 m tall. If the receiving antenna is on the ground The service area is
